How come Federal packs their primers in such a large box? While I'm on the subject, why stack the primers on their sides? I recall 40 years back primers packed like that, but everyone else nowdays had them lying flat and mostly the same side up. Makes loading primer tubes a real PITA. I have always read and heard that one should avoid touching the primers, but it is almost unavoidable with the Federals. Is there some trick I'm missing?
